That's what I use on Unix to recursively search for a pattern (XXXX) in .c and .h files. The single quotes are "tics" -- the character below the tilde in the upper left corner of the keyboard.
I appears that that doesn't work in Red Hat Linux, maybe because the "tic" means something else in linux? The part of the command within the tics works on linux, recursively finding c files, but it does something different when I enclose in it tics.
Anyone know how to search recursively for patterns in files on linux? Tnx.
